MANET is an infrastructure less wireless network. The on demand routing protocol AODV provides an efficient performance in the routing process of the ad hoc networks. The distance vector is the basis of the AODV reactive routing protocol. The criterion set for selecting the route is done on the hop count basis in the AODV routing protocol. This pro...

As the world is progressing towards 5G technology, its primary requirement is high throughput, low latency, high spectrum and energy efficiency and guaranteed QoS. High throughput is achievable when the user (UE) and the base station/Macro eNodeB (MeNB) are close to each other. This is achieved by using femtocell or Home eNodeB (HeNB). It is a kind...

In recent years, a plethora of new metaheuristic algorithms have explored different sources of inspiration within the biological and natural worlds. This nature-inspired approach to algorithm design has been widely criticised. A notable issue is the tendency for authors to use terminology that is derived from the domain of inspiration, rather than ...

We present a novel robust and secure steganography technique to hide images into audio files aiming at increasing the carrier medium capacity. The audio files are in the standard WAV format, which is based on the LSB algorithm, while images are compressed by the GMPR technique which is based on the Discrete Cosine Transform and high-frequency minim...

Hadoop is a leading framework for processing and analyzing big data. MapReduce is a programming model for processing data in parallel and distributed computing environment. One of the issues in HDFS is the number of disk I/O operations involved in fetching input data blocks to memory from disk for every task. Since data-intensive tasks expect predo...

The ascendance of the smart grid concept has provided high hopes of developing an intelligent network that is capable of being a self-healing grid and ability to overcome the interruption problems. We developed a MATLAB-based system to examine the effect of jamming for smart grid applications in improving the reliability of the smart grids via MCS ...

Biclique cryptanalysis is a recent technique developed for key retrieval of block ciphers. In this paper, biclique attack is carried out on full-round, PRESENT-80 block cipher. Here, the biclique is constructed using independent related key differential cryptanalysis. Matching with precomputation is used for the analysis for other rounds. The compu...

The ant colony optimization (ACO) is a population-based metaheuristic algorithm for the optimization problem, inspired by the foraging behavior of ants in the ant colony. One of its variants, the elitist ACO, further reinforces itself with the additional pheromone deposit to find the best path. Even though this usually leads to converging on the so...

A circular patch antenna with double slots has been proposed for multiple band applications. The proposed Pac-man antenna works in the range of C and X band. The antenna has been structured and broke down for FR4 substrate with dielectric constant of 4.4. This reception antenna can be utilized for wireless neighborhood (WLAN 2.324 GHz) applications...
